Project Details

GTPases are the intracellular light switches of the enzyme world, acting as key regulators of signal transduction and the flow of information within the cytoplasm. The goal of this project is to carry out a global mapping exercise, examining the totality of the human GTPome (consisting of over 150 GTPases). This will be achieved by using protein network analysis to establish individual protein/protein interactomes for each GTPase, and then merging these together to provide an atlas for human GTPases. This resource will then be integrated with genome wide expression data and catalogues of post-translational modification to seek for patterns in how GTPases act and are themselves regulating in the cell – with the goal of identifying novel pathways to regulate these proteins in health and disease.

  • Experience with bioinformatic approaches and/or coding experience 

This can be taken full-time or part-time (12months FTE) project commencing in October 2024, based at RVC's Camden campus.


Partially funded: The lab will be covering the project costs, with the MRes student expected to meet the course fees and their living expenses.

International applicants are welcome to apply but must be able to fund the difference between "Home" and "Overseas" tuition fees. Please note that EU/EEA and Swiss national students may no longer be eligible for the “Home” rate of tuition fees, dependent on personal circumstances (including immigration status and residence history in the UK) and UK government rules which are currently being developed. For up-to-date information on fees for EU/EEA and Swiss national students following Brexit please see our fees and funding page. 

How to Apply

Deadline: Sunday 14th July 2024
